I picked up a set of 84 Z28 Wheels (15" Alloys), for my '60 Impala recently, and now that I'm going to put them on, I find I need the correct lug nuts. Problem is, according to the Napa catalog, the 84 used a metric lug bolt! I've seen these wheels on a few old cars, was just wondering if anyone here has used them, and how the dealt with this problem? Seem my options are: change the studs to metric (but will the metric shank fit the SAE holes) or find SAE nuts that will work with these wheels. Any info would be appreciated. Thanks.
